IMPROVEMENT IN FURNACES FOR SMELTING ORES.

Specification forming part of Letters Patent No. 141,912, dated August19, 1873; application filed June 30, 1873.

To all whom fit may concern:

Be it known that I, EDWARD BALEACH, Jr., a resident of the city ofNewark, in the county of Essex and State of New Jersey, have inventedcertain new and useful Improvements in Smelting-Furnaces for Orcs, Src.;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it pertains to make and use it, reference being had to theaccompanying drawings which form part of this speciication.

The great difficulty with furnaces in common use is that'they will notstand intense heat but afew daysordinarily aboutaweekand then they haveto be rebuilt or repaired, necessitating a great loss of time and theexpenditure ofthousands of dollars per annum. Besides this, the furnacesfrequently burst when lled with molten ores or metals, thereby entailinga heavy loss, and being attended with danger to life as well asproperty. The object of this invention is to overcome, 'as far aspossible, these difficulties.

In the drawings hereto annexed, Figure l is a side view of a furnacecombining my improvements. Fig. 2 is a longitudinal section. Fig. 3 is ahorizontal section; and Fig. 4 an end view.

A is the rechamber, and is constructed in the ordinary manner. B is afurnace for melting ores, metals, &c. C is the water-trough surroundingthe sides and bottom of the furnace. D D are pipes for conducting thewater into the trough 5 and E E are discharge-pipes, through which thewater passes out of the trough. F F are gates or lids, which cover theopenings through which the ores or other materials are thrown into thefurnace. Said gates slide upon rollers a a on the top edge of thefurnace; or they may be operated in any other convenient manner. G isaflue, through which the heat, &c., passes from the lire-chamber intothefurnace; and H the liuc connecting with the chimney. I is an outlet forthe matter contained in the furnace; and K is an annular chambersurrounding the dischargeflue I, in which the water circulates aroundsaid discharge-flue.

This invention consists in surrounding a furnace, on its sides andbottom, with a trough iilled with water, and constantly supplied with astream of cold water entering at or near the bottom, and discharged ator near the top, of the trough, substantially as shown. By this meansthe water is prevented from generating steam, and the walls of thefurnace are enabled to withstand 4the heat, and will endure probably foryears instead of only a few days, as heretofore.

`The trough may be continuous, extending all around the furnace; or itmay be made in sections, and each section provided with a supply-pipe,and a discharge for the water, sub stantially as shown in the drawingsaccompanying this specification.

The trough surrounding the sides of the furnace should be high enough tocover the point occupied by the ores or other matter within the furnace,and two inches, more or less, in width, as circumstances may require.

The trough may be made of cast or wrought metal; and used, in somecases, without the inner lining of fire-brick, when the purpose forwhich the furnace is to be used will admit of What I claim as new, anddesire to secure by Letters Patent, is-

A furnace for smelting ores or other purposes,having its bottom andsides surrounded by a trough or troughs of running water, substantiallyas and for the purposes herein set forth and described.

In testimony that I claim the foregoing I I have hereunto set my handand seal this 24th day of June, 1873.
